If the calibration does not work on your board, 3323ba6a0f4SBin Meng select this option and provide a hardcoded TSC running frequency with 3333ba6a0f4SBin Meng CONFIG_TSC_FREQ_IN_MHZ below. 3343ba6a0f4SBin Meng 3353ba6a0f4SBin Meng Normally this option should be turned on in a simulation environment 3363ba6a0f4SBin Meng like qemu. 3373ba6a0f4SBin Meng 3383ba6a0f4SBin Mengconfig TSC_FREQ_IN_MHZ 3393ba6a0f4SBin Meng int "Time-Stamp Counter (TSC) running frequency in MHz" 3403ba6a0f4SBin Meng depends on TSC_CALIBRATION_BYPASS 3413ba6a0f4SBin Meng default 1000 3423ba6a0f4SBin Meng help 3433ba6a0f4SBin Meng The running frequency in MHz of Time-Stamp Counter (TSC). 3443ba6a0f4SBin Meng 3458ef07571SSimon Glasssource "arch/x86/cpu/ivybridge/Kconfig" 3468ef07571SSimon Glass 34758f542deSBin Mengsource "arch/x86/cpu/queensbay/Kconfig" 34858f542deSBin Meng 349fe5b9b44SSimon Glasssource "board/coreboot/coreboot/Kconfig" 350dd84058dSMasahiro Yamada 3518ef07571SSimon Glasssource "board/google/chromebook_link/Kconfig" 3528ef07571SSimon Glass 35358f542deSBin Mengsource "board/intel/crownbay/Kconfig" 35458f542deSBin Meng 355dd84058dSMasahiro Yamadaendmenu 356
